Abstract

A peripheral face of a cooling drum (111) to be driven and rotated in one direction has a predetermined gap relative to an extruding die (101) of an extruder. An extrusion nozzle (105) which communicates with a resin flow path is provided at an end of the extruding die (101) in the die wheel rotation direction, and has a plurality of engaging-element-molding openings (105b) spaced at equal pitches in a width direction thereof. Molten resin extruded from the extruding die (101) onto the peripheral face of the cooling drum (111) is cooled when passing through the resin flow path, and when it is extruded from the extrusion nozzle (105) in half molten state, simultaneously an up/down vibrating means (106) which vibrates vertically opens or closes the engaging-element-molding openings (105b) to mold engaging elements (12) successively, each having a thickness in the molding direction increasing gradually as it goes downward. By change of pressure in the extrusion nozzle (105) by the opening or closing of the up/down vibrating means (106), the engaging element (12) in which lateral widths of front and rear faces (W1, W2) thereof in the molding direction thereof are different is obtained.
Therefore, it is possible to obtain a molded surface fastener in which the engaging elements (12) having diversified dimensions and shapes and excellent physical property are molded integrally, and a molding apparatus and molding method based on a novel molding mechanism, which facilitates maintenance control, ensures a high productivity and is capable of molding the engaging elements (12) having novel shapes and physical property on the substrate (11) easily.
